Armstrong Number : A number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself.
For example 153 is an Armstrong number since 1*1*1 + 5*5*5 + 3*3*3 = 153
In Java Programming We design a code which determine whether given number is Armstrong Number or Not.
Source Code :
<pre class="brush: java">class arm
{int armstrong(int n)
{
if(n==0)
return n;
else
return (n%10)*(n%10)*(n%10)+armstrong(n/10);
}
public static void main(String ar[])
{
arm a=new arm();
int x,y=153;
x=a.armstrong(y);
if(x==y)
{
System.out.println("Given No. "+y+" is a Armstrong No.");
}
else
{
System.out.println("Given No. "+y+" is Not a Armstrong No.");
}
}
}
</pre>
